There's characters from the newer manga series, Fushigi Yuugi the Legend of Genbu. The second Tamahome is the male lead, that transforms into a girl when he uses his powers. The blondie in the back is one of the other stars. Same with the center guy. Those last two characters actually appeared in the original Anime, as ghosts that tested Miaka's resolved and power by encasing her in ice.

I'm really curious about what this story is about, considering the mix of characters.
